Do Pre-Workouts Make You Gain Weight?

Some users worry that pre-workouts contribute to weight gain. However, this is typically due to misunderstanding certain ingredients. The truth:

• Creatine may cause water retention, not fat gain. – Water is stored inside the muscles, leading to a fuller appearance but not body fat accumulation.
• Pre-workouts do not contain calories. – Unless the supplement has added sugars, it will not contribute to fat gain.
• Some pre-workouts improve fat metabolism. – Thermogenic ingredients like green tea extract and L-carnitine may aid fat-burning.

Answer: Pre-workouts do not lead to fat gain, but creatine-containing formulas may cause temporary water retention.

Can Pre-Workout Supplements Break a Fast?

Intermittent fasting (IF) practitioners often wonder whether pre-workouts interfere with their fasting window. The truth:

• Calorie-free pre-workouts do not break a fast. – If the product has no sugar or protein, it will not significantly impact fasting benefits.
• Amino acids and sweeteners may have a minor effect. – Some pre-workouts contain BCAAs or artificial sweeteners, which could trigger a minimal insulin response.
• Stimulants and nitric oxide boosters do not affect fasting. – Caffeine, citrulline, and beta-alanine do not impact fasting metabolism.

Answer: Most pre-workouts are fasting-friendly, but those containing BCAAs or calories may technically break a fast. By separating fact from fiction, users can make informed decisions about pre-workouts and understand their real effects without falling for common myths.
